Abstract

The invention discloses a driving method and system for forward driving and backward anchoring. For solving the problem of interference between a roadheader and a sliding type temporary supporting device, and meanwhile solving the problem of sliding down of roadheader large-slope driving, the roadheader is driven by an advancing jack arranged on a reversed loader to move along a slide rail on thereversed loader, the sliding type temporary supporting device is arranged on the upper part of the roadheader and supports alternately with advancing of the roadheader to realize front-face normal driving, bolt supporting is conducted on the rear face of the sliding type temporary supporting device, and an operator platform is arranged on the symmetrical side end of a hydraulic roof bolter. The driving method and system has the advantages that a travelling way of the roadheader is improved, the problem of the interference between the roadheader and the sliding type temporary supporting deviceis solved, meanwhile the problem of sliding down of roadheader large-slope driving is solved, the driving speed is greatly increased, and thus parallel operation of driving and supporting is achieved.

Description

technical field [0001] The invention relates to the field of coal mining machinery, in particular to a tunneling method and system. Background technique [0002] In the current coal mining excavation system, in order to prevent the interference between the excavation machine and the sliding temporary support device, when the excavation reaches a certain length, it is necessary to stop the excavation to carry out subsequent support work, which limits the excavation speed ; In addition, the existing roadheader adopts crawler type walking, and there is a problem of sliding when encountering large-slope excavation, which also hinders the excavation work. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a kind of tunneling method of the front anchor after digging, including a roadheader, a loader, a sliding type temporary support device, and a hydraulic bolter; The problem of interference b...
